IPC: G01N21/88
Filed: 1994-12-20
Abstract: PURPOSE: To evaluate an abnormal part easily and reliably with a simple configuration by a scattered light source with a geometrically known brightness change as a light source. CONSTITUTION: A light source 1 where brightness changes uniformly geometrically as a light source, is obtained, for example, by transmitting light from a surface-scattering light source through a filter whose transmittance changes continuously. Then, transmission light through an object 2 to be inspected or reflection light reflected from the object 2 to be inspected is received by a light reception device 4 and the amount of change in the quantity of light is used as an evaluation index for appearance deterioration of a failed part. Rays are bent and a brightness which is different from original brightness is detected at a part of a defect 3.  Namely, where there is no defect 3, a known change rate is obtained and a detection signal is obtained where the brightness changes successively, but the order is inverted at the position of the defect 3 and no uniform change can be achieved, thus detecting the defect 3.
